Disarm anti theft system

I was at the mall today and locked my 1989 Buick Reatta, I'm assuming that someone tripped the anti-theft system. When I returned to my car the security light in the dash was blinking as well as the light indicating the parking lights being on. When attempting to start my car the radio and ac turn on but nothing else. Does anyone know how to bypass the anti-theft system?

The security light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterperates this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

SOURCE: anti theft system -can't start car

The price is forbidding our small income expenses. . .BUT if you can
determine my explanation below that your bypass is compatible with ours?
We, I, my wife and baby, are confined in the seculed place in Hayfork
mountains. . .I am seeking for main stand-alone switcher that turns off
against fuel pump, against inner dome light, against rear trunk lid light,
against auto transmission and against four door lock actuators . . .I
successfully made it run with bypass starter relay and hot wired down to
gas tank pump and it runs well but "service immediately" light stays on..
and auto transmission starts on 3 rd gear that stalls engine, it wont start
on second gear. . .when arrived home on uphill road it wont go up so I
drove it on reverse and finally parked here. . .
I KNOW it is a few steps ahead where stand-alone switcher are. I am going
to follow the dome light's wire down to the place where relay-switchers
are. . or follow gas pump wire that I assume can be very hard way to do. .
but before I go ahead that if you can tell me where those switchers for

SOURCE: Turn off security light on my 1992 cadillac deville

I had that same problem and it took me forever to figure out what was wrong. You are probably using an aftermarket key as was I. The stupid little plastic/metal chip in the shaft of the key is for the security system. Sometimes if you insert the key and turn too fast it sets off the security system. To solve the problem go get another key made from a different key maker, they cost around $15-20. Or, insert the key slowly and turn the ignition slowly. Or go get a good key from the dealer, I've heard it may be ~$50 for this key but it should work the best. FYI I still just use my aftermarket key and just deal with the occasional no start wait 3 min ordeal. Good luck.

Hi,

My name is Ben and I'm your guru, i.e., mentor, an influential teacher or popular expert: a management guru. - origin from Sanskrit, 'weighty, grave', for today.

WARNING!

Unless you have shop technical manual,please don't even think about trying to disarm your anti-theft system because there is an easier solution. I'm assuming that you don't have the full Shop Service Manual. If you do, then you know that a shop manual costs at least $100.

So why did I say: Don't even think about it? Your anti-theft device is capable of causing problems that you don't want to deal with. If you have the dealer do the job, the cost can be prohibitive. The anti-theft device tells the on-board computer to shut off the fuel flow and to disengage the starter circuitry.

SOLUTION: Go on eBay and buy an anti-theft bypass module for $10-$20 depending on the year and make of your vehicle.

As you evaluate my advise.solutions and suggestions, there are a few things you must keep in mind:

• I did not diagnose your problem and am therefore only able to evaluate what you tell me. For example, if you ask me a fuse location, that doesn't mean that I can tell you the reason why the fuse blew. I can only react to the information that you provide. So please judge my suggestions accordingly.
• A thorough diagnostic approach involves the use of technical equipment, such as voltage meters. scanning equipment and other sophisticated devices. Diagnostic tools can be borrowed from AutoZone for FREE:
• Lastly, fixing one problem can very easily reveal a problem with something that you might consider unrelated. If that happens, you might want to view me as being incompetent.

The panic alarm sounds


it sounds like one of your door switches is setting off the alarm. Or you hood or trunk switches.

Anti-Theft -Perimeter The perimeter anti-theft system consists of the following:
  • door lock cylinder disarm switches
  • liftgate lock cylinder disarm switch
  • generic electronic module (GEM)
  • door open warning lamp switch
  • pulse stretcher module (wagon only, is located between the rear license plate housing and bracket)
  • keyless entry remote transmitter
  • hood switch/bracket assembly
-----------------------------------------------------------------------------------------------------------------------
Principles of Operation
Perimeter Anti-theft
The perimeter anti-theft feature provides an audible and visual alarm when unauthorized access to the vehicle is detected. When an intrusion is detected by any door or liftgate ajar switches, or the hood and trunk tamper switches it sends a ground signal to the GEM. When the GEM receives a signal indicating intrusion into the vehicle, the GEM supplies a ground signal to the horn control relay and the park lamps relay. The relay closes, supplying the power which activates the horn and the park lamps. The pulse stretcher module applies to wagons only. Due to the distance between the liftgate disarm switch and the GEM, the disarm switch signal is not present long enough for the GEM to recognize. The pulse stretcher module receives pulse input when switch is turned to unlock. The pulse stretcher module holds the pulse active for about 60ms so the GEM can recognize the signal and disarm the system. The perimeter anti-theft feature does not arm until 20 seconds elapses after locking the vehicle. The perimeter anti-theft device will disarm only when
  • unlock is pressed on the keyless entry remote transmitter.
  • keyless entry keypad code is entered.
  • door, luggage compartment lid or liftgate lock cylinder is turned to unlock.
  • ignition switch position changes to run or start.
Inspection and Verification
  1. Verify the customer concern by operating the system.
  1. Visually inspect for obvious signs of mechanical and electrical damage.


Visual Inspection Chart Mechanical Electrical
  • Lock cylinder disarm switches
  • Hood switch
  • Luggage compartment lid switch

Car won't start.Theft light blinks,clicking sound under hood and thumping like horn wants to go off.Seems like it's stuck in anti theft mode


anti theft light should blink every few seconds.

try disconnecting the battery for 15 minutes.

Anti-Theft-Perimeter The perimeter anti-theft system consists of the following components:
  • anti-theft indicator (THEFT)
  • remote anti-theft personality (RAP) module
  • hood switch
  • keyless entry remote transmitter
  • deck lid ajar switch
NOTE: The remote entry features will not function when the ignition switch is in the RUN or ACC position.
Up to four keyless entry remote transmitters (15K601) can be programmed at one time.
The keyless entry remote transmitters :
  • Are programmable.
  • Must be set at the same time.
  • House four buttons.
  • House three buttons (Mexico Anti-Theft System only).
Programming
Refer to Section 501-14B.
Inputs and Outputs
The remote anti-theft personality (RAP) module receives input from the following components for anti-theft operation:
  • Hood switch.
  • Deck lid ajar switch.
  • Keyless entry remote transmitter.
  • Power door lock switches (LH and RH).
  • Door courtesy input.
The RAP module distributes output to the following for the anti-theft system:
  • Power door unlock relay.
  • Power door lock relay.
  • Liftgate unlock relay (Wagon)
  • Park lamps relay.
  • HORN relay.
  • Dome lamp.
  • THEFT indicator.
  • Deck lid release.
Arming
The anti-theft system can be armed if:
  • The ignition switch is in the OFF position.
  • The panic alarm is off.
  • All doors are closed.
NOTE: If a door is open, the anti-theft system is prearmed and waiting for all the doors to be closed. The THEFT indicator will remain illuminated for up to 30 minutes waiting for all the doors to be closed. If a door remains open after 30 minutes, the THEFT indicator will turn off and the system will return to a disarmed state. After all doors are closed and the 30 second prearm (continuous THEFT indicator illumination) is complete, the system is armed.
NOTE: If the theft LED does not flash after 30 seconds, check the LED FLASH PID to see if the feature is enabled.
The anti-theft system will be armed when the lock button on the keyless entry remote transmitter is pressed, all doors are closed and 30 seconds have elapsed.
When the system is armed, the THEFT indicator will flash quickly until the system is triggered or disarmed.
Disarming
NOTE: Using a key in a door lock cylinder to unlock is not a valid method of disarming the anti-theft system.
Untriggered System
NOTE: If the driver arms the system and remains in the vehicle, an untriggered system can be disarmed by turning the ignition switch to the ON position.
An untriggered alarm system can be disarmed by pressing the unlock button on the keyless entry remote transmitter.
Triggered System
NOTE: If the hood or trunk are open when the system is armed, it must be closed and opened again before it can trigger an alarm.
An armed anti-theft system can be triggered by the following conditions:
The deck lid door, liftgate, hood or any door is opened using a key, inside door handle, hood release, etc.
  • The keyless entry remote transmitter can activate a panic alarm which is similar to the anti-theft alarm, but does not cause the THEFT indicator to flash.
A triggered alarm system can be disarmed by:
  • Pressing the unlock or panic button on the keyless entry remote transmitter.
  • Turning the ignition switch to the ON position.
Alarm State When Battery Power Is Cycled
When the RAP module is supplied power the first time at the vehicle assembly plant, the system will be in the disarmed state. The RAP module will remember whether it is armed, disarmed or triggered in its non-volatile memory. When the battery positive cable is removed and then reconnected, the system will return to the state it was in just before the battery was disconnected. If the system is in any prearm state, then the system will return to a disarmed state when the battery is disconnected and then reconnected.

1 Answer

Replaced the alternator, now anti theft won't disable


The ignition lock anti-theft switch (19A438) detects if the ignition key cylinder is broken or "slam pulled" during a theft. The ignition lock anti-theft switch is always monitored by the remote anti-theft personality (RAP) module. This allows the alarm system to be triggered in the case that the ignition lock anti-theft switch detects tampering of the ignition key cylinder (even in the event that the alarm is not active at the time).
Refer to the Section 501-14B for more details on the keyless entry remote transmitter (15K601).
The door open warning lamp switch (14018) communicates to the RAP module through the generic electronic module (GEM). This input to the RAP will cause the anti-theft alarm to be sounded if the anti-theft alarm was armed.
The door disarm switches are assembled into both LH and RH lock sets. The door disarm switch must be triggered before the mechanical lock unlocks. This is to prevent the anti-theft alarm from activating when it should have been disarmed.
The RAP module controls the anti-theft system and is the brains of the keyless entry system. The RAP module communicates with the GEM to request that the interior lights be turned ON/OFF with use of the keyless entry remote transmitter, and the GEM communicates to the RAP to inform when the door is opened. Refer to Section 418-00 for inter-module communication.
The RAP module has three wire connectors attached to it:
  • The antenna for the keyless entry remote transmitter.
  • 26 circuit connector (C256).
  • 22 circuit connector (C257).
In addition to the perimeter alarm that uses the door open warning lamp switch, the RAP module also uses the ignition lock anti-theft switch and the autolock/relock feature to prevent theft of the vehicle. For a full description of the autolock/relock system, refer to Section 501-14B .
The THEFT LED is found on the instrument panel between the tachometer scale and the needle pivot point. The LED is illuminated during prearming and flashes when armed or triggered.
Prearming and Arming the System
The system can be armed if:
  • The ignition is OFF.
  • The PANIC alarm is OFF.
  • All doors are closed.
There are two ways to prearm the system:
  • Press the LOCK button on the transmitter.
  • Open a door, press the power door lock button and close the door.
After 30 seconds the system will be armed and the theft indicator in the cluster will flash every two seconds.
Disarming an Untriggered System
An armed system will be disarmed with one of these valid actions:
  1. Pressing the UNLOCK button on the transmitter.
  1. Placing a key in the door and turning to UNLOCK.
  1. Turning the key to RUN or ACC.
The anti-theft alarm can be triggered by the following conditions:
  • The ignition cylinder is damaged with or without the RAP being armed.
  • A door is opened without disarming the armed RAP module.
The remote transmitter can activate a panic alarm which is similar to an anti-theft alarm, but does not deactivate the starter or cause the theft indicator to flash.
Disarming a Triggered System
If the system has been triggered, (the horn honks, the lights flash, and an external starter interrupt relay is engaged), the system can be disarmed by:
  1. Pressing the UNLOCK or PANIC button on the transmitter.
  1. Putting a key in the door and unlocking the door.
  1. Turning the ignition to RUN/ACC (Turning the key to RUN/ACC will not disarm an alarm that has been triggered by the ignition lock anti-theft switch.).

Section 13-11: Anti-Theft System, Active 1998 Windstar Workshop Manual DESCRIPTION AND OPERATION Anti-Theft Alarm System NOTE: The system immediately monitors the ignition key lock cylinder upon removal of the key from the ignition. It is not necessary to arm the system for ignition key lock monitoring.

The anti-theft alarm system:
  • protects the vehicle from unauthorized entry into the passenger compartment, engine compartment and cargo area.
  • monitors the status of the ignition key lock cylinder.
  • is controlled by a remote anti-theft personality (RAP) module. The remote anti-theft personality module also controls the electronic door lock functions. Refer to Section 01-14B for more details.
  • when armed, detects unauthorized entry into the passenger compartment by using an input from the GEM module regarding the state of the door or liftgate (open or closed).
  • protects the engine compartment with a hood switch which is located on the LH cowl vent panel and is part of windshield wiper motor wiring (17A477) .
  • triggers an alarm if the ignition lock cylinder is forcibly removed from the steering column.
Once triggered, the system responds by:

    34bdf35.gif
Components The system is composed of the following components:
  • remote anti-theft personality (RAP) module with integral antenna
  • alarm indicator LED
  • door lock cylinder switch RH, door lock cylinder switch LH
  • liftgate door lock cylinder switch (220A40)
  • hood switch (part of windshield wiper motor wiring (17A477))
  • ignition lock anti-theft switch (19A438)
The following vehicle components are also used by the anti-theft alarm system:
  • generic electronic module
  • power door lock switch (14028)
  • door open warning lamp switch (14018)
  • autolamp relay (14N089)
  • horn relay and bracket (13853) and horn (13832)
  • low beam headlamps
  • rear lamps (13404) and parking lamps (13200)
  • starter relay
  • door lock relays
  • keyless entry remote transmitter (15K601)
--------------------------------
Disarming an Untriggered System NOTE: A perimeter alarm will "shut off" after 165 seconds, but the system is still triggered and is not disarmed.

An armed but untriggered perimeter anti-theft system can be disarmed by one of the following four events:
  1. Unlock the doors by pressing the keyless entry remote transmitter (15K601) UNLOCK button once.
  2. Unlock any door with a key.
  3. Turn ignition switch to RUN or ACC.
  4. The remote entry PANIC button will disarm the anti-theft system only when the perimeter alarm is triggered and sounding.
------------------------------------------------
System Triggering NOTE: Although the remote entry PANIC alarm is not associated with the monitoring of the vehicle, the user will frequently say that the theft system was triggered when actually the keyless entry remote transmitter PANIC button was inadvertently pressed. A panic alarm will not flash the THEFT indicator.

The alarm can be triggered by the following events if the system has been armed and has not been disarmed first:
  • Open any door or liftgate.
  • Open the hood (16612) (if the hood was open when the system was armed, it must be closed before it can trigger the alarm).
  • Dislodge the ignition key lock cylinder.
  • The anti-theft system may be triggered inadvertently when the module is disconnected and then reconnected. To avoid inadvertent alarm triggering, disconnect the smaller 22-way connector first.
When the system is triggered the perimeter alarm will operate as follows: The remote anti-theft personality module will pulse the following outputs at approximately 1.3 Hz, 50 percent duty cycle for two minutes 45 seconds for North America. NOTE: Other perimeter alarms can be programmed for the system.

  • low beam headlamps
  • parking lamps
  • horn
  • THEFT indicator
The perimeter alarm can be retriggered, after a perimeter alarm has sounded for 165 seconds. After a perimeter alarm has timed out, if any trigger input is first seen as normal and is then seen in its trigger state, the perimeter alarm will be retriggered. The perimeter alarm can be triggered a total of three times between an arming sequence and a disarm event. An active panic alarm will be deactivated when a perimeter alarm is triggered (a perimeter alarm overrides a panic alarm).

Anti-theft system seems to have been activated?


Some months ago I began starting the engine of my 2001 Chrysler 300M but turned it of before it really started "was sloppy with the key". The anti-theft system went on for some unknown reason. I disarmed it by disconnecting one of the battery connections under the hood with a wrench. I connected it again, the anti-theft system was off but the battery was dead. Battery was OK after recharging, I have had no trouble since then.

I'll assume you used the remote here (like most of us do) to arm the alarm. Try turning the key in the door lock - turn it to lock the car (which arms the alarm), and then unlock it (which should disarm it). Do this a couple of times if need be, and it should disarm and allow you to start the car.
